Installation (Tilt Door)
Step 1
:
Locate the centre of the top edge of the garage door and mark it on the inside face. With a level set plumb at this mark,
draw a vertical line on the mounting surface above the door. (IF a ceiling surface suitable for marking exists, extend the
line to the ceiling and mark the ceiling. Open the door and plumb up from the centre mark made on the door to the
ceiling, if one exists, and mark the ceiling. Determine the rise of the high arc of the door. Use level to measure rise on
mounting surface above door. Use the table below to determine the distance the front end bracket should be mounted
above the top of the door when closed.
HIGH ARC RISE
MOUNTING DISTANCE
100 cm
200cm
100-200 cm
330 cm
200-300 cm
450 cm
Make the appropriate measurement and mark the
vertical line at this point.
Step 2:
Attach the bracket provided directly to the structure or the addition with lag screws or bolts and self locking nuts so that
one leg of the bracket provides a shelf upon which the front end of the rail may be rested and subsequently attached.
The leg of the bracket forming the shelf should be at the horizontal mark made in
Step 1.
The centre hole in this leg
should be aligned with the centre of the door opening or the vertical line. The other leg of the bracket, which is to be
attached to the structure may be above or below the mark as the situation may require.
Step 3:
Place the front end of the rail on the bracket attached in
Step 2
, and drop one of the 6mm x 50mm carriage bolts
through the hole in the end of the rail and the centre hole in the bracket. Run one of the 6mm nuts on the end of the bolt
a few turns. This will temporarily hold the rail in place while the back end is swung upward and rested on a step ladder.
CAUTION: IF ADDITIONAL HEIGHT IS REQUIRED, BE CERTAIN THAT THE MEANS USED PROVIDES A STURDY
AND STABLE NON-SKID PLATFORM. PULL THE CARRIER RELEASE ARM TO A VERTICAL POSITION AND
SLIDE THE OUTER HALF OF THE CARRIER TO THE REAR OF THE RAIL. THIS WILL PREVENT THE DOOR
FROM STRIK
ING THE LEVER
. At this time the door can be opened to its high arc position. It will be
necessary to support the door so that it will remain in this position. Position the rail over the centre of the top
section of the door.
Lower the back end of the operator so that the bottom of the rail is about 13mm above the door edge at the high arc
position (Fig 13A). Do not allow the door to support the operator, as this will cause a false measurement to be taken
and possibly damage the door. Support the operator in the same fashion as before and measure the distance from the
ceiling to the selected frame mounting slot. The length of the rear vertical supports will not be greater than this
dimension.
Step 4:
A rear mount must be constructed to secure the rear of the operator to the ceiling. The distance from the operator to the
ceiling structure has already been determined in
STEP 3
. Measure and cut the appropriate length of perforated angle
iron or other suitable metal required to suspend the operator. The operator frame plate is 165mm wide. The vertical
supports should be 82mm from each side of the centre line. Construct the mount and secure it to the structure in the
ceiling. Secure the operator to the mount. The mount must be braced to minimise lateral movement in all directions.
